Prof. Irwin is a Professor in the Department of Applied Ecology at the North Carolina State University. Prof. Irwin received her PhD in Biology from the University of Vermont followed by a post-doc at the University of California at Davis. She subsequently held positions as Assistant and Associate Professor at the University of Georgia and Dartmouth College, and she has been a research scientist at the Rocky Mountain Biological Laboratory for 28 years. Her current research topics span multiple-species interactions, pollination biology and disease ecology, with a focus on the effects of antagonists on the ecology and evolution of plant-pollinator mutualisms and on how plant interactions with both mutualists and antagonists shape and constrain selection on floral traits.
